hereof.

My invention relates to an improvement in an attachment for butting lathes and has for its object to provide an attachment whereby the bulls will give greater service andcapable of being easily and readily attached and detached.

Another object is to provide a device in which the polishing wheels, for (BXSHI PlB an emery, a cloth and a brush wheel will all be in proximity so that no time will be wasted in moving from one wheel to another; also to provide a device that will be easy to construct and cheap to manufacture l/Vith these and other ends in View my invention consists in certain novel features of construction and combination of parts as will be hereinafter fully described and pointed out in the claim.

In the accompanying drawing which represents a sectional view of my improved device, 1 is a suitable frame or support providedwith bearings 2 in which rotates the shaft 3. A belt wheel 4 is located on the shaft 8 at 5. The shaft 3 is exteriorly threaded at 6 and provided with a threaded longitudinal recess 7. l

8 is a screw-threaded mandrel tapered at 9 provided with a flange 10 near one end thereof.

11 is a small hole. running transversely through the flange 10 the object being that a small bar may be inserted therein when it is desired to attach the mandrel to or detach it from the shaft 3.

12 are two small washers preferably two inches in diameter which clamp a buff wheel 13 against the flange 9, and 14 is a nut which securely locks the same.

It will be seen that although the diameter of the opening in the center of the bull wheel be greater than the diameter of the mandrel the bull wheel will be securely held in place by its two washers 12 and nut l4.

15 is a brush wheel located on the tapered portion of the mandrel J and 16 is a cutting wheel carried by the shaft I have only shown one bull wheel carried 0 Y the mandrel 9 but more than one may be used if desired.

it will be readily seen that with my inrproved device that bull wheels may be used until they have been practically worn away instead of discarding them when they have worn down to the level of the five or six inch flanges that are ordinarily. used to clamp the hull wheels in position. The three polishing wheels also being in close proximity do away with any waste of tin 1 that would be occasioned if the wheels were on different machines.

Having thus described my invention, what I claim is:

A builing lathe comprising a fork shaped frame with suitable bearii'igs, a shaft supported in said gearings, a pulley mounted rigidly on said shaft between said bearings, said shaft having at one end an exteriorly threaded portion, a threaded recess extending lon itudinally thereof, a mandrel, exteriorly t readed at one end to engage the above mentioned recess, the other end of said mandrel having a tapering threaded extremity, a threaded cylindrical portion merging therewith, a collar extending around said mandrel and formed integral therewith, said collar se arating the two threaded end portions 0 said mandrel, a. polishing wheel upon said shaft, a polishing wheel upon the threaded cylindrical ortion of said mandrel and a second 130 ishin wheel upon the tapered extremity of sai mandrel.

This s eeification signed and witnessed this 3rd ay of October A. D. 1%)10.
